  1. 1. Modulation Properties of Vertical Cavity Light Emitters

    Author : Renaud Stevens; KTH; []
    Keywords : Semiconductor lasers; VCSEL; high-speed modulation; fibre optic networks; datacom; RCLED; plastic optical fibre;

    Abstract : It is estimated that, between the year 2000 and 2003, thenumber of online Internet users will grow from 250 millions to500 millions. This growth results in rapidly increasing demandfor fibre-optic communication bandwidth, occurring at alllevels: from access and local area networks (LANs) tometro-area networks (MANs). READ MORE

  2. 2. Processing technologies for long-wavelength vertical-cavity lasers

    Author : Fredrik Salomonsson; KTH; []
    Keywords : VCSEL; vertical-cavity laser; semiconductor laser; long-wavelength; DBR; oxidation; wafer fusion; InGaAs; semiconductor processing;

    Abstract : Vertical-cavity surface-emitting lasers (VCSELs) areattractive as potential inexpensive high-performance emittersfor fibre-optical communication systems. Their surface-normalemission together with the small dimensions are beneficial forlow-cost fabrication since it allows on-wafer testing,simplified packaging and effective fibre-coupling. READ MORE

  3. 3. Broadband Receiver Electronic Circuits for Fiber-Optical Communication Systems

    Author : Stavros Giannakopoulos; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; photodetector; broadband amplifiers; data communication; VCSEL; distributed amplifiers.; receiver front-end; short-haul interconnects; InP DHBT; SiGe HBT; TIA;

    Abstract : The exponential growth of internet traffic drives datacenters to constantly improve their capacity. As the copper based network infrastructure is being replaced by fiber-optical interconnects, new industrial standards for higher datarates are required. READ MORE
